Specification of Letters Patent.

Patented Aue". 27, 1912.

Application filed January 8, 1912. Serial No'. 669,939.

To all 'wh-0m t may concern: y l

Be it known that 'L/Grnonon V. BENNING- HOFF, a citizen of the United States, residf .tires for vehicles; and the object of the improvement is to' provide a balanced spring construction for tires which 1s strongf and durable and imparts resiliency without the need of pneumatic inflation; and the invention consistsl in certain novel features of construction and in the arrangement and combination of the parts as shown and described in this specification and vthe accompanyingI drawings and pointed out in the claims.

ln the drawings, Figure 1 is an elevation of a wheel having a' spring tire made in accordance with my improvement, a portion of the outer casing of the tire being broken away to show the arrangement of the inner springs and expanding rings. Fig. 2 is an elevation of a portion of the springs and the eXpandiblc and collapsible metal rings, without the outer casing. Fig. 3 is a crosswise sectional view of the tire showing the arrangement of the springs in relation to the outer casing. Fig. 4 is a lengthwise sectional view'of a portion of the supporting,l ring or hand and one of the expandingr rings attached thereto. Fig. 5 shows a sectional view from the inner side of one of theparts of the rino sections; and Fig. 6 shows a similar view of the outer part of the ring section and an end View of the same. showing the slot for the insertion of the other part. Fig. 7 is a sectional view similar to Fig. 4 Yof a inodication in the arrangement of the sup.- porting springs for the ring section.

, Like numerals of reference refer to corresponding parts in the several views.

The numeral 10 designates the wheel which has a metal rim 11 attached to the outer ends of the spokes.

The numeral 12 designates the outer casing of the spring tire which is preferablyv made of rubber in the usual manner and is attached to rim 11.A The casing 12 prefer in two part-s 15 and 16, the part ,15' being arranged with a loop 17 on each of its ends into which the ends of the vpart 16 are 'I slipped, a pin 18 on the part- 16extending within the lengthwise slot 19 in loop 17 so thatA the parts cannot become disengaged fronrone another by the ends of part 16'V slipping out of the loops 17.

The rings 14 are shaped to conform to the tubular inner sidev or the opening `within the casing 12, and the parts 15 and 16 of the rings 14 are held firmly against the inner.

sides of the casing 12 by the'springs 20 and I21, one end of the springs 2O and 21 being attached to the parts 15 and 16,-and the othervends of said springs bein attached to a ring or rim 22 .which 'is preerably made of two thicknesses of sheet metal and extending around within the casing 12 about midway between the sides ofthe same in a continuous band orv ring 22. .The springs 20 y.and 21-perferably extend to 'parts 15 and 16 from opposite sides of the same, as showin in Figs. 1, 2 ande.y Though the modified form shown in Fig. 7 would serve a good purpose in l: alancing\the action ofthel'ring 14, I find, however, that 'with the springs 2O and: 21 extending from opposite sides of the :ring 14 and so continuing around the tireforA the different rings 14, said rings are better braced against'the shocks brought to bear upon the tire from all directions.

Itis apparent that with the: two parts 15 and 16 inserted one within the other, or with telescoping ends, that said lparts may 4slide back and forth lupon one another thereby.

allowing the springs 20 and 21 free actjn'n.

The springs 20 and 21 are preferably made broad, as shown in Fig. 3, and of sulicient thickness.to give the requiredstrength to f withstand the shocks which will naturally come upon a resilient tire and according to the size of the tire and the weight of the I vehicle. The rings 14 pressing against the resilient rubber band 13 and casin 12 in combination with the springs 2O an 21 and the double spring rim or band 22 give a' comi bined resiliency and holding power which enables the tire to withstand the heaviest shocks.

I claim as new:

1. A tire comprising a resilient tubular casing, a supporting hand extending around said casing within the same, a series of collapsible rings around said supporting band to bear lagainst the inner side of said tubular-casing, anda supporting sprin attached:

to each side of said supporting and and attached to each of said collapsible rings, said springs extending in opposite directions 5 from said collapsible rings to said band.

2.. A tire comprising a resilient tubularcasing, a sup ortmg band extending around said casing Within the same, a series of rings around sald supporting band to bear against 10 the inner side of said. tubular casing, said 15v casing.

3. A tire comprising aresilienvt tubular casing, asupporting band yextending around Vimplies of thsvpatent-may be obtained for ve cents each, by addressing the Commissioner of tateuts,

ress each of said said casing wit-hin the same, a series of rings karound said supporting band to bear against spring support for each of said parts on ysaid band, said leaf sprin s extending in opposite directions from eac of Asaid rings. In testimony whereof .I have affixed my signature 1n the presence of two witnesses.
